A Specication of Letters Patent.

Patented Feb. 6, 191% Application filed December 21, 1914. Serial No.$78,258.

To all 'whom t may concern.' l

Be it known that I, VVILLARD D'RICHARD- soN, a citizen of the UnitedStates, residing at Columbus, in the county of Franklin and State ofOhio, have invented certain new and useful Improvements in WallStructures, of which the following is a specification.

My invention relates to wall structures and it has forl its principalobject the provision of such structure whereby a thin brick veneer maybe practically applied to an ordinary backing or burden bearing wall,thus giving to such wall an impervious'facing of any desired color ortexture. In this connection, my structure' also is such that the nishedwall will have the appearance of a solid structure of the ordinarystandard sized brick now in use, the thickness of this brick beingapproximately two and three-eighths inches and its length approximatelyeight and one-fourth inches. I-Iowever, my facingbrick is of such widththat its Weight as compared to a standard brick is materially reduced,which naturally reduces .its cost of manufacture and its cost ofshipment.

Specifically stated, my invention has for its object the provision of aplurality of burden bearing units and a plurality4 of facing units, eachbeing provided with coperating dove tail projections extending outwardlycentrally from one of their faces in a direction at right angles totheir thickness dimensions.

A further object of vmy invention resides in so constructing my wallthat there are no continuous joints to the same from exterior tointerior, thbrick veneer overlapping the joints of the common or burdenbearing units, thus making the thinnest practical wall strictlyimpervious to moisture.

-The preferred .embodiment of my -invention is shown in the accompanyingsheet of drawings, in which similar characters of reference designatecorresponding parts, and in which:

Figure 1 shows a section of a wall in end view with my facing unitssupplied, Fig. 2 is a view in perspective of a wall constructed inaccordance with my invention., Fig. 3 is a view in perspective of one ofthe facing units, Fig; i is a view in perspective of ene of the burdenbearing units, and, Fig. 5 is a view similar in nature to Fig. l, butshowing the veneer applied to both the interior and exterior faces ofthe burden bearing units.

n In .these views, the facing unit or brick 1s designated generally bythe reference numeral l, and is shown as being provided on its rear facewith a centrally disposed rearwardly projecting tongue 2 of dove-tailna-v ture, in that its extreme rear portion is of greater thickness thanits connecting or neck portion 3. These dove-tail projections arepreferably centrally disposed have all of their longitudinalcorners'rounded and are of considerably less thickness than thethickness of the facing unit as a whole, in order that they may coperatewith similar dovetail projections 4 also centrally disposed andextending forwardly in a direction at right angles to the thickness ofeach of the burden bearing units 5. These burden bearing units 5 may beprovided with a single dove-tail projection, as shown in Fig. 1, or theymay be provided on both their rear and forward faces with theseprojections, as shown in Fig. 5. For purposes of lessening the weight ofthe burden bearing units, I have provided each With a plurality ofapertures 6 located as may be desired to accomplish the result sought.In order that these facings may be made without cracks' and also have aflat surface to lie on when being burnt, vI have made the front face ofeach, the rear face fromwhich the dove-tail for- ,mations project andthe rear face of these formations flat and in parallel planes.

From the foregoing description, it will appear that the formation 2 uponeach of the facing units is similar to the formation 4 upon each of theburden bearing units and, since these projections are centrally disposedas regards the thickness of each, it follows that if they are arrangedtocoperate to securely bond to each other, a wall will be providedwhereinl there are no continuous joints through the same from exteriorto interior as regards horizontal mortar joints and by the well knownstaggered arf rangement of vertical joints of the two units, nocontinuous joints will appear in this d1- rection, the brick veneer ineach case overlapping the joints of the burden bearing units. It nust,therefore, be apparent that I have provided a type of structure whereina wall may be provided having all the appearances of an ordinary brickconstruction and having corresponding properties as re- 110 'gardsstrength'. "Ihis construction may be had in a very eiicient manner andat a greatly reduced cost, the peculiar nature of the dove-tailprojections insuring a perfect and lasting bond between the facing andburden bearing units.

What I claim, is:

A wall structure having a relatively thin facing veneer and made up of aplurality of superimposed backing units of such thickmess as to extendthrough and form the burden bearing portion of the wall and qf theheight and length of a standard brick and having parallel upper andlower faces, each of said units having a longitudinally extending,centrally disposed dovetail lrib formed along its front face, the facingvei 'neer comprising thin slabs of facing material of the length andheight of a standard of the backing units that the vertical jointsbetween the slabs lie out of alinement with the vertical joints betweenthe backing units.

In testimony whereof I affix my signature in presence of two witnesses.
